THE RISK

Medium Risk

Why edit_dns_record needs a policy

DNS record modification is a Write action because it alters configuration reversibly. However, severity is high rather than medium because DNS changes can impact domain resolution, email delivery, and service availability if misconfigured by an agent. The tool operates on production infrastructure (Porkbun domain management) where errors have significant blast radius.

From the tool's definition Tool description states it 'Modifies an existing DNS record' — a reversible change operation. The name 'edit_dns_record' and description confirm Write category semantics (update/modify data).

Documented attack patterns abuse exactly the kind of access edit_dns_record gives an agent:

POLICY

How to control edit_dns_record

PolicyLayer is an MCP gateway — it sits between your AI agents and Porkbun MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for edit_dns_record:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "edit_dns_record": {
      "limits": [
        {
          "counter": "edit_dns_record_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

edit_dns_record stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Porkbun MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
